Some U-Haul 24' trucks up for sale now have them with TBI. They are 93 to 95 vintage so they probably have the 16197427 PCM running them.
They have an ALLISON AT545 transmission behind them that might be good for a tow rig but it is a four speed auto with no overdrive so it would have to be geared taller to work.

I thought about turning one into a car hauler but don't want to see that ugly pig sitting at my house all the time.
